Question Water Pump 99 E320

Good Day: After replacing one idler pully, I am pretty sure my engine noise is now the water pump bearing. There is a little play in the shaft. The Parts Store shows three brands as replacement parts. They are Laso, Graf, and Hepo. Is one better than the other?

Also, it appears if I get the correct sockets the repair should be pretty straight forward. Any tricks, I should know about?

Thank you in advance for your advice!
GW

The "Graf" pump is the best of the 3 listed.

You need a special wrench to counterhold the fan clutch nut.

Thank you for the advice. This unit does not have a mechanical fan, only electric. The water pump shaft is threaded but there is nothing there. Anything else I should know?

I am not sure about the E320 engine, but on the e300D engine I had to remove the timing mark. It might be worth a subscription to alldatadiy.com for an exploded parts description.

Drop the belt and run the COLD engine for 30 secs to see if the noise disappears in order to confirm its an accessory device.
